摘　　要：主要研究复平面C中单位圆盘U上的强螺形函数子族的第三项和第四项系数估计问题,即主要研究强α次的殆β型螺形函数和强α次殆星形函数的第三项和第四项系数估计问题.所得结果推广了已有的一些结论.In this paper,the third and fourth coefficient estimations for the subclasses of strongly spirallike functions in the unit disc U of complex plane C are mainly investigated.That is,the third and fourth coefficient estimations for strongly almost spirallike functions of type β and order α and strongly almost starlike functions of order α are mainly studied,and some known results are generalized.

关 键 词：强α次的殆β型螺形函数 强α次殆星形函数 单叶解析函数 系数估计
